BACKGROUND

1. Field

The following description relates to a method of advertising to a mobileterminal connected to a femto base station, and a communication methodof a mobile terminal, a femto base station, and a macro base station.

2. Description of Related Art

Femtocells may be classified into various types of femtocells, forexample, a personal femtocell that may be used to provide an ultrahighspeed transmission service within a predetermined area, a commercialfemtocell to provide an advertisement service for sales promotion of ashop, and an authorized femtocell to provide a location service. Mostfemtocell applications focus on a user's convenience but do notsufficiently consider benefits to various installers and administrators.

In a personal femtocell, a femtocell installer and an administrator maybe substantially the same as a service beneficiary, and therefore,various administrative rights need not be distinguished. However, in thecommercial femtocell, there is a need to further distinguish the rightsof a femtocell installer with that of a femtocell administrator in orderto protect commercial rights.

DESCRIPTION

The following description is provided to assist the reader in gaining acomprehensive understanding of the methods, apparatuses, and/or systemsdescribed herein. Accordingly, various changes, modifications, andequivalents of the methods, apparatuses, and/or systems described hereinmay be suggested to those of ordinary skill in the art. Also,description of well-known functions and constructions may be omitted forincreased clarity and conciseness.

As described herein, a macrocell refers to a coverage area of a macrobase station, and a femtocell refers to a coverage area of a femto basestation.

FIG. 1 illustrates an example of a network that allows a mobile terminalto identify and connect to a neighbor femtocell.

Referring to FIG. 1, the network in which the mobile terminal identifiesand connects to the neighbor femtocell includes a macro base station101, two femto base stations 103, and a mobile terminal 105. It shouldbe appreciated that the number of macro base stations, femto basestations, and mobile terminals are not limited to the example shown inFIG. 1. For example, the network may include one or more macro basestations, one or more femto base stations, and one or more mobileterminals.

The macro base station coverage area includes a macrocell. The macrobase station 101 sets up a broadcast channel section 109 to identify afemtocell within a downlink broadcast channel 107 of the macrocell ofthe macro base station 105. The macro base station 101 reports thebroadcast channel section 109 to at least one femto base station 103 inthe macrocell of the macro base station 105.

For example, the macro base station 101 may be linked with the femtobase station 103 positioned in the macrocell of the macro base station105, and maintain and renew a database including connection information.The connection information may include, for example, information aboutlinked femto base stations 103, information about shops in which thelinked femto base stations 103 are located, information about the linkedfemto base stations 103 with the macro base station 101, and the like.

For example, the macro base station 101 may renew the database at a timewhen a femto base station 103 is added to the macrocell of the macrobase station 105, at a preset time, or at any other desired time.

The femto base stations 103 may offer various services, for example,real-time advertisements and event announcements of shops to the mobileterminal 105 as the user of the mobile terminal is within the coveragearea of the femto base stations or passing by the shops in which thefemto base stations 103 are located.

For example, the femto base stations 103 may be linked with the macrobase station 101 to attract customers passing by the shops in which thefemto base stations 103 are located. The femto base stations 103 may besynchronized with the macro base station 101 to be linked with the macrobase station 101.

The mobile terminal 105 may set a femtocell exploration mode of themobile terminal 105 to automatically identify a femtocell. For example,when the femtocell exploration mode of the mobile terminal 105 is set to‘ON,’ the mobile terminal 105 may detect the broadcast channel section109 in order to identify a femtocell in the macrocell and identifywhether there is a neighbor femtocell. During femtocell explorationmode, the mobile terminal 105 may detect one or more femtocellscorresponding to one or more femto base stations 103, which are withinthe macrocell of the macro base station 101 and which are available forthe mobile terminal 105 to connect with.

The mobile terminal 105 may select a femto base station 103 from amongthe one or more detected femto base stations 103 based on a userpreference of the mobile terminal 105 and/or information about neighborfemto base stations 103 of the mobile terminal 105 received from themacro base station 101. Accordingly, the mobile terminal 105 may beprovided with a unique advertisement service of the femto base station103 while located within a femtocell of the femto base station 103.

For example, the unique advertisement service of the femto base station103 may include products sold by a shop in which the femto base station103 is located, an advertisement for the shop, an advertisement servicefor an event held by the shop, and the like.

As an example, when the shop in which the femto base station 103 islocated is an ice cream shop, an advertisement service for the shop mayinclude an advertisement for a new flavor of ice cream that may bepurchased in the shop, discount information about products “on sale”,discount coupons, and the like.

As described herein, when the femtocell exploration mode of the mobileterminal 105 is set to ‘ON,’ the mobile terminal 105 may detect thebroadcast channel section 109 to identify a femtocell of a femto basestation 103 that is located within the macrocell of the macro basestation 101, and be provided with the a unique advertisement service ofthe femto base station 103 from the femto base station 103. The mobileterminal 105 may be positioned in the same macrocell as the macro basestation 101 and the femto base station 103. The downlink broadcastchannel 107 of the macrocell may be used to identify a femtocell in themacrocell.

The broadcast channel section 109 used to identify the femtocell in themacrocell set in the downlink broadcast channel 107 of the macrocell maybe set at a preset cycle, for example, a cycle of a hundredmilliseconds, two hundred milliseconds, five hundred milliseconds, orother desired amount of time.

Hereinafter, a method including the macro base station 101, the femtobase station 103, and the mobile terminal 105 in which the mobileterminal 105 identifies a neighbor femto base station 103 of the mobileterminal 105 and connect to the femto base station 103, is described.

The macro base station 101 reports information about the broadcastchannel section 109 to the femtocell corresponding to at least one femtocell 103 in the macrocell set in the downlink broadcast channel 107 ofthe macrocell, in 110. For example, the macro base station may report toone or more femto base stations 103 during 110.

The femto base station 103 receiving a report about the broadcastchannel section 109 from the macro base station 101 may set a signal inthe broadcast channel section 109 in order to report the existence ofthe femtocell corresponding to the femto base station 103, in 120.

For example, the broadcast channel section 109 of the downlink broadcastchannel 107 may be set to a single bit or multiple bits.

In 120, the femto base station 103 may set various types of signals inthe broadcast channel section 109 to report the existence of thefemtocell of the femto base station 103, for example, the femto basestation 103 may set a particular bit of the broadcast channel section109 to ‘1’ or set the broadcast channel section 109 to a dummy signal.

When the femtocell exploration mode of the mobile terminal 105 is set toON in 130, the mobile terminal 105 may detect the broadcast channelsection 109 to that identify the femtocell corresponding to the a femtobase station 103 is within the macrocell corresponding to the macro basestation 101.

The mobile terminal 105 may identify a femto base station 103 that isaccessible to the mobile terminal 105 from among the at least one femtobase station 103 that is within the macrocell of the macro base station,based on a measurement result of an intensity of the signal of thebroadcast channel section 109, in 140.

For example, when the measurement result of the intensity of the signalin the broadcast channel section 109 is higher than a preset thresholdvalue, the mobile terminal 105 may identify that there is at least onefemto base station 103 neighboring the mobile terminal 105 and which isaccessible to the mobile terminal 105. As another example, based on theintensity of the signal the mobile terminal 105 may determine that aplurality of femto base stations are neighboring and available, forexample, two femto base stations, three femto base stations, four femtobase stations, or more femto base stations.

For example, the femto base station 103 may set a signal in thebroadcast channel section 109 in order to report the existence of thefemtocell that corresponds to the femto base station 103 when receivingthe report about the broadcast channel section 109 to identify thefemtocell in the macrocell from the macro base station 101.

The mobile terminal 105 may measure an intensity of the signal in thebroadcast channel section 109 received from each neighbor femto basestation 103 of the mobile terminal 105. The mobile terminal 105 mayidentify a femto base station 103 that is accessible to the mobileterminal 105 from among the at least one femto base station 103 in themacrocell based on the measured intensity.

The mobile terminal 105 may transmit position information of the mobileterminal 105 to the macro base station 101, and may transmit a requestfor information about the femto base station 103 which is accessible tothe mobile terminal 105 to the macro base station 101, in 150.

For example, the macro base station 101 may generate a list of neighborfemto base stations 103 and information about the neighbor femto basestations 103 based on the position information of the mobile terminal105 received from the mobile terminal 105, and may transmit thegenerated information to the mobile terminal 105, in 160.

As an example, the information about the neighbor femto base stations103 of the mobile terminal 105 may include information about a shop inwhich each of the respective femto base stations 103 is located orinformation about a discount policy of a connection service offered byeach of the femto base stations 103.

The mobile terminal 105 may select one femto base station 103 from amongthe neighbor femto base stations 103 of the mobile terminal 105 based onthe list of the neighbor femto base stations 103 and the informationabout the neighbor femto base stations 103 received from the macro basestation 101, in 170.

In 170, the mobile terminal 105 may select the femto base station 103 inthe list of the neighbor femto base stations 103 based on a userpreference of the mobile terminal 105 and/or the information about theneighbor femto base stations 103 of the mobile terminal 105.

An example of the list of the neighbor femto base stations 103 of themobile terminal 105 received by the mobile terminal 105 from the macrobase station 101 may include the following contents as shown in Table 1.

TABLE 1 Location of Base Femto base Business Transmission stationstation ID category Policy for use speed a A Cosmetics free Low a BClothing 10 cents/min High a C Entertainment free Medium a D Fast food 5cent/min High (free when receiving advertisements)

In this example, the mobile terminal 105 receives information about fourfemto base stations A, B, C, and D 103 neighboring the mobile terminal105 from the macro base station 101. Accordingly, if a user of themobile terminal 105 prefers a femto base station that provides a hightransmittance speed and a free communication channel, the user of themobile terminal 105 may select femto base station D to receivecommunication from.

That is, the mobile terminal 105 may automatically select or a user ofthe mobile terminal 105 may select the femto base station D whichsatisfies all user preferences from among the femto base stations B andD that provide a high transmittance speed and a free communicationchannel from among the femto base stations A, B, C, and D in the list.

For example, the mobile terminal 105 may use the communication channelprovided by the selected femto base station D. Further, the mobileterminal 105 may be provided with information about a shop in which thefemto base station D is located or information about a discount policyof a connection service offered by the femto base station D from thefemto base station D.

In this example, the femto base station D corresponds to a femto basestation of a fast food restaurant. Accordingly, the mobile terminal 105may be provided with information about a fast food restaurant in whichthe femto base station D is located, information about a sales eventoffered by the fast food restaurant, coupons for discounts offered bythe fast food restaurant, and an advertisement for the sales event.

As another example, the mobile terminal 105 may select a femto basestation 103 based on the information about the neighbor femto basestations 103 of the mobile terminal 105.

For example, the mobile terminal 105 may select a femto base station 103corresponding to information in which a user of the mobile terminal 105is interested in from among information about shops in which therespective femto base stations 103 in the list of the neighbor the femtobase stations 103 of the mobile terminal 105 are located.

As an example, the mobile terminal 105 may select a femto base station103 located in a shop in the list of the neighbor femto base stations103 of the mobile terminal 105, the shop offering a sales event, a shopproviding a coupon of a product for a discount when receiving anadvertisement service, and the like.

As described above, the mobile terminal 105 may automatically select afemto base station 103 from the list of the neighbor femto base stations103 of the mobile terminal 105 by various methods. Depending on thefemto base station 103 selected, the user of the mobile terminal 105 maybe provided with an advertisement service from the femto base station103.

Further, the mobile terminal 105 itself may provide the list of theneighbor femto base stations 103 of the mobile terminal 105 andinformation about events thereof to a user of the mobile terminal 105when selecting a femto base station 103, thereby allowing the users toselect a femto base station 103 themselves.

As another example, a femto base station 103 may be automaticallyselected by the macro base station 101. In yet other embodiments, thefemto base station 103 may be automatically selected by the mobileterminal 105 based on predetermined settings or dynamically adjustedsettings that may be dynamically set by a user. As yet another example,the femto base station 103 may be selected by a user of the mobileterminal 105.

As another example, the macro base station 101 may store a userpreference of the mobile terminal 105 and the information about theneighbor femto base stations 103 of the mobile terminal 105 in advance,and selectively provide a femto base station 103 that satisfies the userpreference based on stored information.

For example, the macro base station 101 may include a database ofinformation about the user preference of the mobile terminal 105 shownin the following Table 2.

TABLE 2 Mobile terminal Age Policy for Transmission Interested ID groupsuse speed business category Others A 20s Free Medium CommunicationSelecting free of terminals, games charge when receiving advertisementsB 30s Free/charged High Restaurants High transmission speed C 40s FreeMedium Sports, book Receiving sports- stores related advertisements

The macro base station 101 may select a femto base station 103 whichcorresponds to the user preferences of the mobile terminal 105 shown inTable 2 from among the information about the neighbor femto basestations 103 of the mobile terminal 105 and provide the femto basestation 103 to the mobile terminal 105.

The macro base station 101 may transmit connection information to themobile terminal 105 to enable an access to the selected femto basestation 103 in the list of the femto base stations 103, in 180.

The mobile terminal 105 may connect to the selected femto base station103 using the connection information received from the macro basestation 101, in 190.

Accordingly, the mobile terminal 105 connected to the femto base station103 may be provided with various communication services andadvertisement services offered by the femto base station 103.

For example, the advertisement services may include a unique voiceadvertisement service of the femto base station 103 and a unique displayadvertisement service of the femto base station 103. For example, theunique voice advertisement service of the femto base station 103 may beprovided to the mobile terminal 105 while the mobile terminal 105 inputsa telephone number and waits for a call to connect.

As described herein, the unique advertisement service of the femto basestation 103 may be provided to the mobile terminal 105 while the mobileterminal 105 waits for data reception about a uniform resource locator(URL) address which the mobile terminal 105 desires to access.

FIG. 2 illustrates an example of a network that allows a femto basestation to offer an advertisement to a mobile terminal connected to thefemto base station.

Referring to FIG. 2, the network for providing the advertisement to themobile terminal includes a counterpart exchange station 201, a femtobase station 203, a mobile terminal 205, and a receiving side mobileterminal 207.

For example, a user in control of the mobile terminal 205 passing by ashop in which the femto base station 203 is located may attempt to calla friend by entering the phone number of a friend that corresponds tothe receiving side mobile terminal 207, to try a call, in 210.

In response to the call being placed by the user of the mobile terminal205, the femto base station 203 identifies a voice call transmittingsignal transmitted from the mobile terminal 205 based on the call beingplaced. Accordingly, the femto base station 203 may provide anadvertisement to the mobile terminal 205 connected to the femto basestation 203, and postpone transmission of the voice call transmittingsignal in response to the identification of the voice call transmittingsignal, in 220.

For example, the femto base station 203 may include a voice calltransmitting signal identification module that may identify the voicecall transmitting signal transmitted from the mobile terminal 205. Thefemto base station 203 may offer a unique voice advertisement service ofthe femto base station 203 to the mobile terminal 205 in response to theidentification of the voice call transmitting signal, in 230.

The femto base station 203 forwards the postponed voice calltransmitting signal to the counterpart exchange station 201, in 240. Forexample, the femto base station 203 may forward the postponed voice calltransmitting signal after a predetermined amount of time elapses.

For example, the femto base station 203 may identify a ringback tonesignal transmitted from the receiving side mobile terminal 207, andaccordingly, the femto base station 203 stops the unique voiceadvertisement service of the femto base station 203 in response to theidentification of the ringback tone signal, in 250.

After stopping the unique voice advertisement service of the femto basestation 203, the femto base station 203 may forward the ringback tonesignal to the mobile terminal 205 to connect a voice call, in 260.

FIG. 3 illustrates an example of a communication method of a macro basestation.

Referring to FIG. 3, the macro base station reports information about abroadcast channel section to at least one femto base station to identifya femtocell corresponding to a femto base station in the macrocellcorresponding to the macro base station set in a downlink broadcastchannel of the macrocell, in 310. For example, the broadcast channel maybe set in the downlink broadcast channel of the macrocell at a presetcycle.

The macro base station receives position information of a mobileterminal and a request for information about neighbor femto basestations of the mobile terminal, in 320. For example, the positioninformation and the request for information may be transmitted from themobile terminal. For example, when the mobile terminal identifies anaccessible femto base station from among the at least one femto basestation in the broadcast channel section, the mobile terminal maytransmit the information to the macro base station.

For example, the information about the neighbor femto base stations ofthe mobile terminal may include information about a shop in which eachof the femto base stations is located. As another example, theinformation may include information about a discount policy of aconnection service offered by each of the femto base stations.

The macro base station generates a list of the neighbor femto basestations of the mobile terminal and information about the neighbor femtobase stations of the mobile terminal based on the position informationof the mobile terminal, in 330.

The macro base station transmits the list of the neighbor femto basestations of the mobile terminal and the information about the neighborfemto base stations of the mobile terminal to the mobile terminal, in340.

In 350, the macro base station may transmit connection information toenable the mobile terminal access to a femto base station.

The connection information to enable the mobile terminal access to thefemto base station may be information about a femto base stationselected by the mobile terminal from among the neighbor femto basestations of the mobile terminal in the list.

FIG. 4 illustrates an example of a communication method of a mobileterminal.

Referring to FIG. 4, the mobile terminal may determine whether afemtocell exploration mode of the mobile terminal in a macrocell is setto ‘ON’, in 410.

When the femtocell exploration mode is set to ‘ON,’ the mobile terminaldetects a broadcast channel section to identify a femtocell that themacrocell set in a downlink broadcast channel of the macrocell, in 420.For example, the broadcast channel section may be set in the downlinkbroadcast channel of the macrocell at a preset cycle.

As a result of the determination in 410, if the femtocell explorationmode is not set to ‘ON,’ or the mobile terminal does not have afemtocell exploration function, the mobile terminal may finish theprocess without performing subsequent operations to 410.

The mobile terminal identifies a femto base station which is accessibleto the mobile terminal from among at least one femto base station in themacrocell based on a measurement of an intensity of a signal of thebroadcast channel section in order to identify the femtocell in themacrocell.

That is, the mobile terminal may measure the intensity of the signal ofthe broadcast channel section to identify the femtocell and compare themeasurement result with a preset threshold value, in 440.

When the intensity of the signal of the broadcast channel sectionmeasured in 440 is higher than the preset threshold value, the mobileterminal may identify that the femto base station is accessible to themobile terminal from among the at least one femto base station in themacrocell, in 450.

The mobile terminal transmits, to a macro base station, positioninformation of the mobile terminal and a request for information aboutthe accessible femto base station, in 460. The mobile terminal receivesrequested information from the macro base station, in 470.

For example, the information received from the macro base station mayinclude a list of neighbor femto base stations of the mobile terminaland information about the neighbor femto base stations of the mobileterminal. For example, the list and the information may be generatedbased on the position information of the mobile terminal.

As an example, the information about the neighbor femto base stations ofthe mobile terminal may include information about a shop in which eachof the femto base stations is located or include information about adiscount policy of a connection service offered by each of the femtobase stations.

The mobile terminal may select a femto base station from among theneighbor femto base stations of the mobile terminal based on the list ofthe neighbor femto base stations and the information about the neighborfemto base stations, in 480.

For example, the mobile terminal may use a preference of a user of themobile terminal and the information about the neighbor femto basestations of the mobile terminal in order to select a femto base station.

FIG. 5 illustrates an example of a method of offering an advertisementto a mobile terminal connected to a femto base station.

Referring to FIG. 5, when the mobile terminal inputs a datacommunication connection signal such as a URL address which the mobileterminal desires to access, the femto base station identifies the datacommunication connection signal transmitted from the mobile terminal, in510.

The femto base station postpones transmission of the data communicationconnection signal in response to the identification of the datacommunication connection signal, in 520.

The femto base station offers a unique advertisement service of thefemto base station to the mobile terminal, in response to theidentification of the data communication connection signal, in 530. Forexample, after a lapse of a predetermined amount of time, the femto basestation may forward the postponed data communication connection signalto an internet server in operation.

In 540, the femto base station identifies a data reception signal aboutthe URL address which the mobile terminal desires to access. Forexample, the femto base station may include a functional module toidentify a data reception signal such as a homepage or a URL addresswhich the mobile terminal desires in order to identify the datareception signal.

The femto base station may stop a unique advertisement service of thefemto base station in response to the identification of the datareception signal about the URL address which the mobile terminal desiresto access, in 550. The femto base station may forward the data receptionsignal about the URL address which the mobile terminal desires to accessto the mobile terminal to connect a voice call.

As described herein, the mobile terminal may include various modes suchas a femtocell exploration mode. However, it should be appreciated thatthe mobile terminal may only have one mode in which the mobile terminalconstantly searches for an available femtocell.

As a non-exhaustive illustration only, the terminal device describedherein may refer to mobile devices such as a cellular phone, a personaldigital assistant (PDA), a digital camera, a portable game console, anMP3 player, a portable/personal multimedia player (PMP), a handhelde-book, a portable lab-top personal computer (PC), a global positioningsystem (GPS) navigation, and devices such as a desktop PC, a highdefinition television (HDTV), an optical disc player, a setup box, andthe like, capable of wireless communication or network communicationconsistent with that disclosed herein.

A computing system or a computer may include a microprocessor that iselectrically connected with a bus, a user interface, and a memorycontroller. It may further include a flash memory device. The flashmemory device may store N-bit data via the memory controller. The N-bitdata is processed or will be processed by the microprocessor and N maybe 1 or an integer greater than 1. Where the computing system orcomputer is a mobile apparatus, a battery may be additionally providedto supply operation voltage of the computing system or computer.

It should be apparent to those of ordinary skill in the art that thecomputing system or computer may further include an application chipset,a camera image processor (CIS), a mobile Dynamic Random Access Memory(DRAM), and the like. The memory controller and the flash memory devicemay constitute a solid state drive/disk (SSD) that uses a non-volatilememory to store data.

The processes, functions, methods, and/or software described above maybe recorded, stored, or fixed in one or more computer-readable storagemedia that includes program instructions to be implemented by a computerto cause a processor to execute or perform the program instructions. Themedia may also include, alone or in combination with the programinstructions, data files, data structures, and the like. Examples ofcomputer-readable storage media include magnetic media such as harddisks, floppy disks, and magnetic tape; optical media such as CD ROMdisks and DVDs; magneto-optical media such as optical disks; andhardware devices that are specially configured to store and performprogram instructions, such as read-only memory (ROM), random accessmemory (RAM), flash memory, and the like. Examples of programinstructions include both machine code, such as produced by a compiler,and files containing higher level code that may be executed by thecomputer using an interpreter. The described hardware devices may beconfigured to act as one or more software modules in order to performthe operations and methods described above, or vice versa. In addition,a computer-readable storage medium may be distributed among computersystems connected through a network and non-transitory computer-readablecodes or program instructions may be stored and executed in adecentralized manner.

A number of examples have been described above. Nevertheless, it shouldbe understood that various modifications may be made. For example,suitable results may be achieved if the described techniques areperformed in a different order and/or if components in a describedsystem, architecture, device, or circuit are combined in a differentmanner and/or replaced or supplemented by other components or theirequivalents.
